I have no clue but I just want the thanks
When combined the dominant one takes over. Therefore, you see the dominant trait physically, not the recessive one. However, genetically, they are both there.
Betaxolol belongs to the drug class of beta blockers wherein these drugs block the action of the beta adrenergic receptors in different organs, including the heart and the bronchial tissues. Oral beta blockers (i.e. Propranolol) must be avoided because there can be additive effects of the ophthalmic drops and the oral drug and may cause severe bradycardia (and/or asthma exacerbation, if the patient has asthma).
When an action potential does arrive at the terminal, the neurotransmitter must be quickly and efficiently released from the terminal<span> and into the synaptic cleft. The neurotransmitter must then be recognized by </span>selective receptors on the postsynaptic cell<span> so that it can pass along the signal and initiate another action potential.</span>
